[PATCH 1/4] arm64: dts: imx8mm-beacon: Migrate sound card to simple-audio-card

From: Adam Ford
Date: Thu Aug 31 2023 - 07:51:46 EST


Instead of using a custom glue layer connecting the wm8962 CODEC
to the SAI3 sound-dai, migrate the sound card to simple-audio-card.
This also brings this board in line with the imx8mn-beacon and
imx8mp-beacon.
